Shure this month introduced the versatile SE115m+ earphones for iPhones, which can do a lot more beyond play music. A three-button panel located on the cable has buttons to adjust volume, change songs, or answer or end calls without having to remove the earphones. Users can listen to music and switch to a phone call with the click of a button.

The earphones work with the iPhone 3G S and certain iPod models, the company said. iPhones use proprietary headphone jacks, which is why Shure released the $120 earphones specifically for the mobile device.

The product will only be available this month through Apple's stores and on its through the end of the year. Availability will expand to retailers outside Apple next year.
